You mean lambda x: lumberjack(15, x) ?

Yes, that was my mistake.

However this syntax you allow to write lumberjack(%, 15) which is only possible with partial using keyword arguments, like lumberjack (y=15) (given that the second argument is called "y") and in that case I know at least one library on pip doing the job with Ellipsis :

from funcoperators import elipartial elipartial(lumberjack, ..., 15) # gives lambda x: lumberjack (x, 15)

elipartial (lumberjack, ..., 15, ..., 12, ...) # gives lambda x, y, z: lumberjack(x, 15, y, 12, z)

And the lib even provide a decorator to have that kind of syntax using "[" :

partially(lumberjack)[15] would be the same as partial(lumberjack, 15)

So, that functionality does really need new syntax.

Hm, yes. Perhaps elipartial could be aliased and/or made a global built in. Let’s discuss the merits of the statement itself then.
